<p>I run a fleet of the APC ATSes - some of which are coming on 10 years service - with no noted issues beyond some caveats in the f<span style="font-size: 12pt;">irmware update process.</span></p>
<p><br>
</p>
<p>In the absence of details on the error the UPSes threw, the original issue sounds like a faulty device.<br>
</p>
<p><br>
</p>
<p>Eaton are a good alternative but there's certainly nothing wrong with the APC units.<br>

<p class="MsoNormal"><span style="color:black">We run a number (~6 or so) of the APC ATS’ for some of our critical (but only 1 PSU) gear with no issues.</span></p>
<p class="MsoNormal"><span style="color:black">We did however have one that was faulty from new that switched between A&B feeds a bit randomly and was replaced because there was no reason it should have been switching.</span></p>
<p class="MsoNormal"><span style="color:black"> </span></p>
<p class="MsoNormal"><span style="color:black">Have you called APC to try and troubleshoot the issue?</span></p>
<p class="MsoNormal"><span style="color:black">I’m not sure how the ATS could trip the UPS/Breakers as there should only ever be one active circuit unless there’s a fault or overload condition.</span></p>
<p class="MsoNormal"><span style="color:black">What size UPS’ are behind the ATS? 3000VA or so?</span></p>

<p class="MsoNormal">Hi Guys</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">We have a very small server room with one rack drawing around 8 amps.</p>
<p class="MsoNormal">I thought I was clever and installed an APC ATS to run the kit that only has single feel power input.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Well its been a disaster, final straw was 4am today when it caused both UPS’s to error and trip all breakers.</p>
<p class="MsoNormal">Bypassing the ATS fixed it.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">I’m thinking of abandoning the ATS idea or trying another brand like Eaton
</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Does anyone have any thoughts on this?</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Thanks</p>
